Carotid Artery Disease (CAD) is a condition where the carotid arteries become narrowed or blocked (‘occluded’) by a buildup of plaque that is made up of fatty deposits called atherosclerosis.
You have two main carotid arteries that run up the neck and then split into internal and external carotid arteries. The internal carotid arteries supply oxygen-rich blood to your brain. The external carotid arteries supply oxygen-rich blood to your face, scalp, and neck.
Carotid Artery Disease is the result of the main carotid arteries becoming partially or fully blocked with this waxy plaque, preventing adequate blood flow to the brain.
